Обсуждение: Postgres Dropped DB have recovered files how to restore

This morning I accidently deleted my database for my OpenERP accounting. I
did not have a good backup system setup so I was unable to do a system
restore. i did manage to recover the files the drop command removed but I
dont know how to get the DB back into postgres? Can anyone help me with
this. I realy need this db to be restored otherwise I am screwed.

These are the folders I recovered(i think my db was in the \base\19456
folder):

C:\Program Files (x86)\OpenERP
7.0-20141104-021038\PostgreSQL\data\base\19456\ *

C:\Program Files (x86)\OpenERP
7.0-20141104-021038\PostgreSQL\data\base\19456\ *

C:\Program Files (x86)\OpenERP
7.0-20141104-021038\PostgreSQL\data\base\311296

C:\Program Files (x86)\OpenERP
7.0-20141104-021038\PostgreSQL\data\global\pg_internal.init\ *

C:\Program Files (x86)\OpenERP
7.0-20141104-021038\PostgreSQL\data\pg_stat_tmp\ *

I am running Windows Server 2012 R2 and postgres 9.3. Any help wil be much
apreciated I am kind of desperate.

This is what a complete $DATADIR for 9.3 looks like on a Linux source
install:

So if what you show is everything then you are short some important
directories.

I have no idea about Windows filesystems but you may be able to
"undelete" the files, as long as you don't touch the partition for
anything else; search the web for "undelete ntfs".  Once you undelete
you will need to put them back in the right places.  I suggest you get a
disk with twice as much space as the original; make an image copy of the
original disk and don't touch the original anymore.  Then try to
undelete the files from the image.  Use the list Adrian provided as a
guide for what you're missing.

You *may* be able to recover the data, if you're lucky and careful.

that won't work if he did a DROP DATABASE as all the metadata is gone.

It's only very difficult -- not impossible.
